Just to give an example of a time line (keep in mind the dates just like with human females vary)
My first clutch this year, my female shed on 2/26. Around mid to the end of March she started to hug her water bowl and seek the cold side of her enclosure. Then about the middle of April I notice her getting fat from her mid section to her tail, and her color was brighter then normal(the best I've ever seen her). She shed again on 5/15(Post ovulation shed) and laid 8 eggs on 6/29!
SO.....about 20 days after ovulation post ovulation shed, and then about 30 days later EGGS!!!!!
The best thing you can do is watch and catalog her sheds!
hope this helps and good luck!
